Henry Blodget today lays out a scenario where Yahoo reports a stinker, Microsoft pulls its offer, the stock drops 40%, and then MSFT comes back with a new offer - at $25.

If you want to see what can happen when shareholders protest too much, take a look at Cablevision (CVC), where holders last year rejected a $36.26 a share bid from the Dolan family to take the company private. Investors asserted that the offer was too low. And then the cable sector hit an air pocket. Current CVC price: $23.27.

Maybe Jerry Yang should simply call Steve Ballmer and take his money while he can.

Yahoo today is down 12.5 cents, at $28.875. (Or as we used to say in the pre-decimal days, down 1/8 at 28 7/8.)
